A biopsy specimen from the edge of the abdominal lesion demonstrated decreased subcutaneous fat with necrotic fat cells and an inflammatory infiltrate of lymphocytes and plasma cells. Eight months of treatment with topical steroids (diflucortolone valerate, 0.1%) and tacrolimus ointment did not have any significant effect. At a follow-up visit 1 year after the patient's initial presentation, the lesion appeared to have stopped growing, and there was some improvement in its size and depth.
